The radiation oncologist is the best person to answer this question.
I have had patients over the years who have had surgery and radiation treatment and gone throught the same again. Ask about hyperbaric oxygen treatments. This procedure can allow previously irradiated tissues to heal normally after surgery.

Good Luck and stay strong!!
